EU CBAM Verifier Accreditation: July 2026 Update

Actual-emissions reporting under EU CBAM depends on more than a producer’s calculation. The Commission’s verification guidance says declarations based on actual emissions require an independent verifierVerifierAccredited independent third party confirming the SEE is free of material misstatement; any EU or third-country legal person; only values in a verification report count for actuals. Importers receiving "verification reports" from third part accredited by an EU national accreditation body, or NAB. The verifier’s role is to provide reasonable assuranceReasonable assuranceThe assurance level of CBAM verification statements (workbook "Engagement type" dropdown also offers "Limited assurance" — CBAM verification itself is reasonable-assurance). that the embedded-emissions calculation is correct.

That makes accreditation a practical dependency for producers, importers and verification firms preparing for definitive-period declarations. It also creates a timing issue: the legal framework is established, while the network of providers able to accept applications is still developing.

What an accredited verifier does

The non-EU installation operator remains responsible for monitoring and calculating emissions under the applicable CBAM methods. The accredited verifier then examines the monitoring approach, calculations and supporting evidence before issuing a verification reportVerification reportSingle electronic Commission template via the CBAM Registry; minimum content: general identification, verification information (team, visits, materiality applied, data verification incl. FAA per good, precursor verification incl. precursor- for the installation.

The operator transmits the verified data and report through the CBAM RegistryCBAM RegistryEU IT system holding declarant accounts, declarations, verified emissions reports, certificate transactions and (from 2027) the published default carbon prices.. The declarant can retrieve that information for its declaration. The Commission or the competent national authority may review the material, and the national authority may take enforcement action where appropriate.

This sequence matters for supplier onboarding. A declarant should not treat an emissions spreadsheet as equivalent to verified installation data. The calculation, evidence trail, verifier scope and Registry transfer all need to work together.

Where verification companies apply

EU NABs—and EEA NABs after the relevant EEA incorporation—are the bodies competent to grant CBAM accreditation. An EU- or EEA-established verification company will generally apply to its home NAB. If that NAB does not offer the service, another NAB may be available.

The route is different for a third-country verification company. Commission guidance says it may apply to any NAB offering the service. That does not mean every NAB accepts such applications, or that acceptance today guarantees the activity scope a company needs.

Before choosing a route, the applicant should confirm the live NAB offer, applicant eligibility, relevant activity scope and current application process.

What the July snapshot shows

The Commission’s 10 July 2026 state-of-play table was a capacity snapshot, not an accreditation certificate or permanent legal classification. It reported 24 NABs agreeing to provide CBAM accreditation, 11 ready to accept applications, seven agreeing to accredit third-country applicants and four already accepting third-country applications (O; 10 July 2026 snapshot).

Italy, the Netherlands, Poland and Sweden were shown as accepting third-country applications at that date (O; 10 July 2026 snapshot). These names must not be carried forward as a fixed referral list. Provider readiness can change, and a general willingness to accept applications does not confirm accreditation for a particular verification activity.

The guidance also indicated that the first CBAM verifier accreditations were expected around September 2026. That expectation is time-sensitive and must be refreshed before publication or operational reliance.

Build the verification route before it becomes critical

Importers using actual values should ask suppliers which installation will report, who owns the Monitoring PlanMonitoring planOperator's written description of source-stream monitoring, tiers, methods and data-gap procedures; baseline document of the verification., how records will be preserved and how verified data will reach the Registry. Verification firms should identify the appropriate NAB and confirm the application route directly. Producers should retain calculation files, process evidence and source records in a form a verifier can test.

Run a live accreditation-path check instead of relying on a saved July table. Open the current Commission verifier page, confirm the NAB’s current position and document the date and scope of the check. Then align supplier, verifier and Registry responsibilities before the declaration workflow depends on them.
